Day-ahead Optimal Scheduling of Integrated Energy Systems Considering Multi-energy Flexibility Support
The power fluctuation of each subsystem threatens the safe and reliable operation of the whole integrated energy system containing heterogeneous energy subsystems such as electricity,gas and heat,and in this regard,a day-ahead optimal scheduling strategy for the integrated energy system that takes into account the multi-energy flexibility support is proposed.An integrated en-ergy system day-ahead optimal scheduling architecture that considers multi-energy flexibility support is constructed by quantify-ing the flexibility supply and demand of multiple energy sources in the integrated energy system,so as to coordinate the output of flexibility resources among the energy subsystems.The results of calculation simulations have verified the effectiveness of the pro-posed scheduling strategy in coordinating the output of flexibility resources and realizing the mutual benefit of multiple energy power regulation capabilities,which improves the economy and reliability of the flexible resource supply of the system.
